ANTI-EXTlNGUlSHlNG'ATTACHMENT FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 243,167, dated June 21, 1881. Application filed March 1, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. SMITH, of

- the city, county, and State of New York, have invented a new and Improved Anti-ExtingnishingAttachmentfor Gas-Burners,ofwhich the following is a full, clear, and exact description.

Figure l is a sectional elevation of my improvement shown as applied to a gas-burner. Fig. 2 is a sectional plan view of the same, taken through the line as m, Fig. 1.

Similar letters of reference indicate corresponding parts.

The obj ect of this invention is to prevent gaslights from being accidentally extinguished.

The invention consists of a conical-topped box, having a central diaphragm, apertures being made very near the middle of the box and the diaphragm to permit the box to be mounted upon a gas-burner. In use the cone of the box stands just below the tip of the gas-burner. At the base of the gas-burnera small aperture is made, through which gas constantly escapes when the gas is turned on for use. \Vhen the gas is lighted at the burner in the usual manner the escaping gas at the pin-hole also ignites and continues to burn. Should the gas at the burner become extinguished by accident or from being blown out, the flame from the pin-hole will immediately ignite the escaping gas from the burner. The conical shape of the box and the central diaphragm serve to protect the pin-hole jet from becoming extinguished except when the gas is wholly turned off by the usual gas-cock.

A represents a gas-burner constructed in the ordinary manner, except that it has a small aperture or pin-hole, B, in its lower part, through which a small stream of gas escapes continuously while the gas is turned on.

O is a small cylindrical box, nearly closed at top and bottom. In the bottom of the box 0, a little at one side of its center, is an opening, D, of such a size as to receive and fit upon the base of the burner A, which supports the v attachment 0. Near the center of the top of the box is a diaphragm, 0, having a circular opening, E, provided with an upwardly-projecting collar or flange, F. The opening E is made-larger than the burner A, to permit the passage of gas and air as well as the burner. The box 0 is provided with a conical top, G, in the apex of whichis an opening a little larger than the gas-burner. When the article is in use the top ot'the cap G stands a little below the tip of the burner A, as shown in Fig. 1.

With this construction, when the gas is turned on and lighted, the small stream of gas escaping from the pin-hole B will take fire and will burn within the box 0; and should the flame at the tip of the burner A be blown out, through ignorance or thoughtlessness, or by accident, the escaping gas will be at once ignited from the small flame at the pin-hole B, so that it will be impossible for the gas-burner light to be permanently extinguished while the gas is turned on. The peculiar construction of this attachment prevents the flame at the pinhole B from being extinguished by air-currents entering the opening in the upper end of the cap G, as the entering blast of air will be distributed around the walls of the cap G, and will not pass through the opening E in the diaphragm C with suflicient force to extinguish the flame at the pin-hole B.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1. An anti-extinguisher attachment for gasburners, made substantially as herein shown and described, consisting of a conical ly-topped box, with central diaphragm and -openings to admit the body of the burner and the passage of gas, as set forth.

2.,In an anti-extinguishing attachment for gas-burners, the combination, with the burner A, provided with an escapeorifice, B, of the conically-topped box and its central diaphragm provided with openings, as herein shown and described.
